DR6 Front 6-Piston Drift Big Brake Kit
The DR6 front big brake kit is built around the DR6 Racing Series — Drift caliper: a two-piece forged 6-piston body with staggered 27 / 32 / 38 mm pistons, paired with solid two-piece iron rotors and application-specific brackets, hats, and braided lines. It targets the things that actually win drift events — repeatable bite, fast pressure rise, clean modulation into lock-up, and predictable release during transitions.

Why Builders Choose the DR6
Drift cars do not need raw stopping distance alone — they need a front axle that responds the instant the driver loads the pedal, then releases without dragging mid-transition. The DR6 total piston area of 50.2 cm² per caliper is sized to deliver strong initial bite on a 330–355 mm rotor without overwhelming hydraulic balance against the OE rear or a hydraulic handbrake circuit.
Two-Piece Forged Body
Two-piece forged aluminum construction keeps caliper weight at 2.50 kg per side without pads, reducing unsprung mass and improving wheel-speed response.
Solid Two-Piece Rotors
Ø330 / 343 / 355 mm solid two-piece rotors use heat-treated high-carbon iron with directional curved-slot faces for clean pad refresh.
Racing Pistons Without Dust Boots
Open-piston construction is designed for high-temperature service intervals, easy seal inspection, and quick rebuilds.
Linear Pedal Feel
Pedal pressure stays linear, and the solid rotor mass holds heat predictably across back-to-back runs.
Vehicle-Specific Engineering
Brackets, hats, and brake-line fittings are built to your chassis, knuckle, wheel offset, and competition use case.

The Bespoke Engineering Process
Every DR6 front drift system is engineered around the vehicle’s front knuckle, hub location, rotor hat offset, wheel barrel, spoke clearance, brake line routing, master cylinder, rear circuit, hydraulic handbrake layout, front brake bias target, and intended drift, time-attack, or rally use. The goal is not a generic universal fit; the goal is a front brake package that delivers repeatable bite, fast pressure rise, clean modulation into lock-up, and predictable release during transitions.
1. Technical Consultation
We review the chassis code, front knuckle and hub setup, wheel spec, master cylinder, rear circuit, hydraulic handbrake use, target front brake behavior, tire package, event format, and whether the car uses OEM or custom front uprights.
2. Data Submission
For OEM knuckles, provide chassis code, knuckle / hub setup, wheel diameter, width, offset, spoke profile, master cylinder, and rear circuit details. For custom front uprights, provide CAD files, technical drawings, hub-face data, rotor mounting dimensions, or accurate bracket mounting-point measurements.
3. Engineering Review & Approval
TTSPORT confirms rotor size, caliper bracket geometry, rotor hat offset, brake line fittings, wheel clearance, brake balance, line routing, and bedding requirements before production begins.
If you are unsure whether your wheel, front knuckle, rotor offset, master cylinder, rear circuit, or hydraulic handbrake layout is suitable, Contact us before ordering so the engineering team can review the build details.

Frequently Asked Questions
What chassis is the DR6 designed for?
The DR6 is a Racing Series — Drift caliper. It is built to order with vehicle-specific brackets, rotor hats, and brake-line fittings, so it can be configured for popular drift, time-attack, and rally chassis running 17 in or larger wheels. Send your chassis details and TTSPORT will confirm fitment before production.
330 mm, 343 mm, or 355 mm rotor — which should I run?
Run 330 mm if you want lower rotational inertia and quicker wheel-speed response on a lighter chassis or shorter session format. Step up to 343 or 355 mm when chassis weight, entry speed, or session length increases the heat load.
Why do the calipers have no dust boots?
Open-piston racing construction tolerates sustained high pad temperatures better than booted street pistons and makes between-session seal inspection faster. It is intended for race-prepared cars that see regular brake service.
Will this throw off my front-to-rear brake balance?
The 50.2 cm² total piston area on a 330–355 mm rotor is sized for strong front bite without overwhelming a typical OE rear or a separate hydraulic handbrake circuit. Re-check brake bias after install, especially if the master cylinder or rear setup has been changed.
Can the rotor rings be replaced separately?
Yes. The two-piece rotor uses a CNC-machined aluminum hat and a heat-treated high-carbon iron ring, so the iron friction ring can be replaced against the original hat to reduce running cost across a season.
Is bedding-in really required?
Yes. The pad and rotor friction couple needs a controlled bedding cycle to transfer pad material onto the rotor face evenly. Skipping this step causes uneven deposits, vibration, and reduced bite under load.
Ready to spec your DR6 drift build?
Send your chassis code, knuckle / hub setup, wheel spec, master cylinder, rear circuit, and hydraulic handbrake layout. TTSPORT will confirm rotor size, bracket geometry, brake balance, rotor hat offset, and line routing before production.

Great tool!
Size: 18in, Style: Sport
Ok - so I do not have a dog!!! I purchased this item for a completely different purpose! I saw someone using this to gather eggs!! I often go to my daughter and son-in-law's homestead to carry out the chores when they need to be out of town! Well, I am a bit on the short side (4'11") and some of the hens KNOW that a short person is going to be gathering eggs!!! I simply could not reach all of the eggs in a couple of the nesting boxes! So, after seeing someone else use this ball launcher as an egg retriever, I bought one! I am now able to reach ALL of the eggs - one at a time with no breakage! It was a game changer for me.
I am sure that it works equally well for dog play!!!

Essential kit for those with fetch dogs
Size: 18in, Style: Sport
Now in our 3rd year, my Brittany and I are down to about 40 fetch tosses a day, some 14,600 tosses a year. The Chuck It launcher wears well, so, figure at least 5 years of use, for 73,000 tosses. That makes for a terrific value!
There are several key benefits of the Chuck It launchers: One is that you can chuck the ball further than you can throw, which allows you to exercise your dog more easily. The second is that you can pick up and launch the ball without touching it, which means NO slime! And, the Chuck It also gives extra reach when you have to retrieve a ball from sticker brambles.
Those are great features for anyone with a fetch dog. If you also happen to have a weak arm or shoulder, the Chuck It launchers provide nice throwing options. I generally throw underhanded. I can't get the full potential range, that way, but, I still get good, long tosses. I curl my second finger above the last bump on the handle, and use a good wrist flick along with arm swing. I've seen others throw side-arm with the Chuck It.
I had originally written a second review for the longer 25M Chuck It. Either I, or Amazon messed up, and it looks like I can have only this one review. So, here are my additional thoughts on the 25M: I bought the 25M so that I could throw the ball even further! The good news is, you really can chuck further, with the longer chucker. The bad news is, those longer throws do require more arm and shoulder strength than when using the 18M. This becomes more obvious when you've done 3 or 4 dozen throws. I would recommend the 25M only for those with the youth and/or strength to get the most out of it. Otherwise, I'd say, go with the 18M.

Must Have for Tiring Out Your Pup
Size: 25in, Style: Sport
The Chuckit! Sport 25M Dog Ball Launcher is an absolute must-have for any dog owner with an active pup! This thing takes fetch to a whole new level—effortless long throws, hands-free pickup (no more slobbery tennis balls!), and a comfortable grip that makes playtime easier and way more fun.
My dog absolutely loves it, and I love that it helps her burn off energy without tiring out my arm. The included medium ball is the perfect size for medium to large dogs, and the durable construction means it's built to last. If you're looking for a simple but game-changing way to upgrade fetch, this is it. Highly recommend!
